5/16 Hi-Tech Pushrods - 6.500 Long

The COMP CAMS 5/16 Hi-Tech Pushrods - 6.500 Long (Part Number 7767-16) are precision chromoly pushrods engineered for high-performance engine builds where valvetrain stability and durability under sustained RPM matter. These pushrods measure 6.500 inches in length with a 5/16-inch diameter and 0.080-inch thick wall construction, delivering the rigid geometry required for accurate valve timing in aggressive cam profiles and high-lift applications.

The Hi-Tech design minimizes deflection under load, a critical factor when running elevated spring pressures or extended valve lift. Chromoly construction provides superior strength-to-weight ratio compared to standard steel, reducing inertial mass while maintaining the structural integrity needed to transfer camshaft motion reliably to rocker arms. The 0.080-inch wall thickness balances durability against unnecessary weight penalty. This set of 16 pushrods covers a complete small-block engine package, and the 6.500-inch length suits many common small-block Chevrolet and comparable applications, though fitment must be verified against your specific block height and rocker geometry.

Builders and engine shops use COMP CAMS pushrods when constructing naturally aspirated performance engines, bracket racing mills, and street-strip combinations where valvetrain reliability is non-negotiable. The Hi-Tech line is suited for applications running higher RPM limits, radical cam timing, or marginal rocker arm geometry where standard pushrods would flex excessively and cause valve timing variance. Installation requires attention to preload specifications and pushrod length confirmation—even a 0.050-inch variance can affect rocker geometry and valvetrain health.
